Abstract: A system and method facilitating the exchange and/or using of a session key (e.g., symmetric key) to facilitate secure communication is provided. The session key can be employed, for example, to encrypt and/or decrypt message(s) that form a dialog between an initiator system and target system(s). “Dialog” refers to bidirectional streams of messages between two endpoints (e.g., initiator system and target system(s)). The systems and methods of the present invention can facilitate, for example, dialog authentication (e.g., ensuring that the initiator and target of the dialog are who they say they are by exchanging security credentials), and, authorization (e.g., only allowing authorized users to send and receive messages). The system(s) and method(s) of the present invention can further facilitate location transparency of service(s) and/or scalable secure monolog(s). The system employs public key/private key asymmetric encryption and/or decryption technique(s) to authenticate and secure information (e.g.
